python图片水印软件pyqt5

python图片水印软件pyqt5

最终效果图如上所示

第一步

先在designer画好软件效果布局

这里默认label标签设置了图片

保存为qianming2.ui 然后在vscode里转成Ui_qianming2.py文件

第二步

编写代码：

import sys

from PyQt5.QtWidgets import QApplication, QMainWindow,QMessageBox

from PyQt5.QtGui import *

from PyQt5 import QtWidgets

import Ui_qianming2

from functools import partial

import requests

from bs4 import BeautifulSoup

#这里是消息提示弹出框的主要代码

class MyWindow(QtWidgets.QWidget):

def __init__(self):

super().__init__()

#消息提示框

def msg(self):

QMessageBox.warning(self,"提示框","输入框不能留空")

# QMessageBox.question(self,"消息框标题","这是一条问答。")

# QMessageBox.information(self,"消息框标题","这是一条消息。")

#主要处理函数

def convert(ui):

text = ui.comboBox.currentText()#返回选中项的文本内容

if text == '个性签':

font = 'jfcs.ttf'

elif text == '连笔签':

font = 'qmt.ttf'

elif text == '潇洒签':

font = 'bzcs.ttf'

elif text == '草体签':

font = 'lfc.ttf'

elif text == '合文签':

font = 'haku.ttf'

elif text == '商务签':

font = 'zql.ttf'

else:

font = 'yqk.ttf'

start_url = '/'

name = ui.textEdit.toPlainText()

if name == '':

myw = MyWindow()

myw.msg()

return

else:

name = ui.textEdit.toPlainText()

data = {

'word': name,

'sizes': '60',

'fonts': font,

'fontcolor': '#000000'

}

result = requests.post(start_url, data=data)

result.encoding='utf-8'

html = result.text

soup = BeautifulSoup(html,'html.parser')

img_url = soup.find('div', class_="tu").find('img')['src']

Urls = start_url + img_url

res = requests.get(Urls)

#引用网络图片地址

img = QImage.fromData(res.content)

ui.label.setPixmap(QPixmap.fromImage(img))

'''

#已用本地图片地址代码

pic=res.content

with open('{}'.format(img_url.split('/')[-1]), 'wb') as f:

f.write(pic)

ui.label.setPixmap(QPixmap(img_url.split('/')[-1]))

'''

if __name__ == '__main__':

app = QApplication(sys.argv)

MainWindow = QMainWindow()

ui = Ui_qianming2.Ui_MainWindow()

ui.setupUi(MainWindow)

MainWindow.show()

ui.pushButton.clicked.connect(partial(convert, ui))

ui.comboBox.activated.connect(partial(convert, ui))

sys.exit(app.exec_())
